novice builder...

Hey! Im starting my first boat ever with ml boatworks laser cut frame for 83 miss rock....seems like I just glue it together...but I don't know what I don't know yet so im looking for as much help as I can get...any tips?..

Make sure EVERYTHING is as square as you can get it.

 

[SayMikey]

Start with a jig to build it on 13 1/4 wide by 48 3/4 inch ply. Find or have someone plane a couple 2x4s straight glue them and screw together for a straight square rigid platform to build from....Thats the very first step. Assemble for trial fit DONT cut or sand anything where the holes for frames are. A tight fit is better than a loose one. Opps what are you building 1/8 or Gas Scale?

1/7th electric ..got jig setup....how glue frames together? Tackwith superglue than epoxy?

 

[SayMikey]

Frames should hold together line them up and use a small very small hammer to set them in place in the tabs. I then use slow epoxy,makes for a slow build time but strong boat

You will get answers both ways on whether to tack then use epoxy or just epoxy everything the first time. I personally epoxy the frames together then mix fiberglass filler with some epoxy and make fillets down both sides of the frames to make the joint stronger.

Here is a link on Phil Thomas's build of his gas scale. The pictures will help you with your build. https://www.intlwaters.com/gallery/thumbnails.php?album=1135

Sweet! How ensure frames stay square...jig will hold it straight but what about square?

Frames should fit together well without CA follow Buddy's and Mikeys tips. I buy a bag of the epoxy mixing sticks(popsicle sticks) and sand the desired radius on the ends and thicken the epoxy with glass fibers or microbaloons to form the fillet radius after the initial epoxy. You may have to use some thin CA before the epoxy when you get to the curved skins to tack things in place. HINT: Thin CA wicks into wood better than thicker epoxy. I use the Wests system with the slow hardener- about 20-30 minutes of working time- dry overnight.. The only hammer I've ever used is a 2OZ. rawhide but if you have a dog-they eyeball it like a chew toy :lol: .

Old machinist trick- 1-2-3 blocks- anyone got a pic?

 

[kim studerus]

Thanks!!ok when u say fillet I am thinking of a sort of thing that's like "caulking the joint...am I correct?

Kinda, You create a rounded area that makes the joint stronger. Sharp corners are perfect places for cracks to start. The chopped glass fibers make a stronger joint than the microbaloons.

 

[kim studerus]

Ok great! So either side of the frame right?

 

[glenng]

All corners.

 

[glenng]

Don't think it's been mentioned yet. Try to keep the back end as light as you can. Boat should balance near the sponson transoms.

 

[Propeler]

chopped glss in every corner of the framework?

how much will your framework weight?

first, dry fit the kit together on a building- jig or board.

make sure everything is square and flat, then use thin CA and a kicker to glue the complete Framework together.

adding some spruce stringer to the front end of the sponsons will help to hold them in position

Now bond the most stressed areas with a small amount of 5 min epoxy.

leave the rest of the frames, they all will be glued after skinning the boat when you seal the hull inside from water with undiluted slow setting epoxy.

This is epoxy and filler I use:

[kim studerus]

What's a kicker?

 

[chris thornton]

What's a kicker?

its the spay stuff you use to make CA set instantly

 

[kim studerus]

Who sells it? Never heard if it? Should I lay carbon fiber in the r

Tunnel to mount motor and electric s to?

 

[Propeler]

No,

no u don't need to lay a sheet of carbon or glass into the engine bay.

it's only a idea of mike to make the bottom of the boat a little bit stronger.

kicker means: accelerator for cyanoacrylate glue, often filled in a spray cans or in a glass bottles with a brush to apply

u can find it in any hobby store or online
